即时消息应用这样实现，每个移动设备101，...，103包括可使用无线通信网络的IP传输业务联系即时消息服务器12的用户应用。The instant messaging application is implemented in such a way that each
当移动设备想要向他的群的其他移动设备通告其存在时，即时消息应用的用户部分建立合适的消息，并利用无线通信网络的IP传输业务寻址到即时消息服务器12。即时消息服务器的IP地址在用户应用处已知。该消息优选地具有在IETF RFC2778“A model for presenceand instant messaging”中定义的格式。When a mobile device wants to announce its presence to other mobile devices of its group, the user part of the instant messaging application creates an appropriate message and addresses it to the instant messaging server 12 using the IP transport service of the wireless communication network. The IP address of the instant messaging server is known at the user application. The message preferably has the format defined in IETF RFC2778 "A model for presence and instant messaging".
即时消息服务器12处一收到该消息，就检查属于接收消息的发射方101归属的群的所有移动设备的身份，产生并发送消息到这些移动设备102，103，通告他们移动设备101正可用于接收即时消息和给出其当前位置。Upon receipt of the message at the instant messaging server 12, it checks the identities of all mobile devices belonging to the group to which the
根据本发明的一个实施方式，当移动设备101想要向属于他的群的其他移动设备通告其存在时，即时消息应用在上述定义的消息中增加包括关于移动设备101的位置的信息的域。According to one embodiment of the invention, when a
为此，移动设备101需要知道其位置。如果移动设备101装备有GPS接收机的情况下更是如此。如果移动设备从使得它确定其位置的无线通信网络接收信息的情况下也是如此。To do this, the
根据本发明的另一实施方式，即时消息服务器13一旦接收到带有从如上定义的移动设备101接收的存在信息而在预定义的对应域中不包含位置信息的消息，就会优选地通过询问位置服务器13确定移动设备101的位置。According to another embodiment of the present invention, once the instant message server 13 receives a message with the presence information received from the
通过利用无线通信网络的IP传输业务，经由无线通信网络发送请求到达位置服务器13。根据本领域技术人员所熟悉的方法之一，位置服务器13可实现移动设备101的位置估计，在本说明中不再详细说明。The request is transmitted via the wireless communication network to the location server 13 by utilizing the IP transfer service of the wireless communication network. According to one of the methods familiar to those skilled in the art, the location server 13 can realize the location estimation of the
从位置服务器13一接收到响应，即时消息服务器就产生除用户101的存在信息之外包括用户101的位置信息的消息，并将其发送到属于移动设备101的群的其他移动设备102，103。Upon receipt of the response from the location server 13, the instant message server generates a message including the location information of the
在其他移动设备102，103上的用户即时消息应用显示关于移动设备101的存在状态以及其位置的信息。结果，其他移动设备102，103被通告移动设备101的位置，而不打扰移动设备101，也不需要占用话音信道呼叫和询问他的位置。The user's instant messaging application on the other mobile device 102, 103 displays information about the presence status of the

根据本发明，该消息还包括域23，表示移动设备101的位置。According to the invention, the message also includes a field 23 indicating the location of the
域23中的位置信息可以小区标识符例如BSS，BBS标识符或接入点标识符的形式包括在消息中，这些标识符表示移动设备101位于无线通信网络的哪个小区，例如哪个BSS或哪个接入点。这提供了低准确率。The location information in field 23 may be included in the message in the form of a cell identifier, such as a BSS, a BBS identifier or an access point identifier, which indicates in which cell of the wireless communication network the
可替代地，域23中的位置信息可对应于移动设备101的地理座标。该解决方案准确得多，在移动设备101配备有GPS接收机时为优选。Alternatively, the location information in field 23 may correspond to geographic coordinates of
可替代地，域23中的位置信息可以是逻辑信息，比如邮政编码，街道地址，大厦名称等。该替换方法需要使用将用户地理上的“x，y”位置翻译成这样的逻辑信息的地理编码功能。位置服务器13联系用于处理这种翻译的GIS(地理信息系统)。对本领域技术人员清楚的是，如果在即时消息服务器12和GIS之间有可用的接口，即时消息服务器12本身可直接在GIS开始请求翻译而不需要位置服务器13的干涉。Alternatively, the location information in field 23 may be logical information such as zip code, street address, building name, and the like. This alternative method requires the use of a geocoding function that translates the user's geographic "x,y" location into such logical information. The location server 13 contacts a GIS (Geographic Information System) for handling this translation. It is clear to a person skilled in the art that if there is an interface available between the instant messaging server 12 and the GIS, the instant messaging server 12 itself can start requesting translations directly at the GIS without the intervention of the location server 13 .
图3表示根据本发明的移动设备101的内部结构。移动设备101包括即时消息用户应用，其与存储于即时消息服务器13的服务器应用兼容。即时消息用户应用包括软件模块31，用于根据带有存在信息的即时消息协议优选地根据IETF RFC 2778产生消息，消息中另包括关于移动设备101的位置的信息。Fig. 3 shows the internal structure of the
优选地，移动设备101包括连接到软件模块31的GPS接收机32。GPS接收机32提供移动设备101的位置信息到软件模块31，用于产生消息。Preferably, the
在本发明的另一实施方式中，如果移动设备101从无线通信网络接收形式为小区、BSS或接入点标识符的位置指示，就不需要GPS模块。In another embodiment of the invention, a GPS module is not required if the
图4表示根据本发明的即时消息服务器12的内部结构。FIG. 4 shows the internal structure of the instant messaging server 12 according to the present invention.
即时消息服务器12包括到无线通信网络的接口41，用于根据本发明接收即时消息的模块42，用户群控制器43，用于根据本发明传输消息的模块44和可选的位置模块45。The instant message server 12 comprises an interface 41 to a wireless communication network, a module 42 for receiving instant messages according to the invention, a subscriber group controller 43, a module 44 for transmitting messages according to the invention and an optional location module 45 .
即时消息经由接口41接收，并提交到用于接收即时消息的模块42。模块42检查接收的即时消息的格式。Instant messages are received via interface 41 and submitted to module 42 for receiving instant messages. Module 42 checks the format of the received instant message.
如果表示发送移动设备的位置的位置域23未填充虚信息，则该信息从消息中提取并存储在群控制器43。If the location field 23 representing the location of the sending mobile is not populated with dummy information, this information is extracted from the message and stored in the group controller 43 .
优选地，群控制器43检查位置相对于已存储的位置是否发生变化，如果发生了变化，则触发模块44传输即时消息到群控制器43中注册的作为属于发送移动设备的群的所有移动设备。然后模块44产生包括由发送移动设备提交的位置信息以及优选地包括存在信息的消息，并发送到恰当的接收方。Preferably, the group controller 43 checks whether the location has changed relative to the stored location, and if so, the trigger module 44 transmits an instant message to all mobile devices registered in the group controller 43 as belonging to the group of the sending mobile device . Module 44 then generates a message including the location information submitted by the sending mobile device, and preferably presence information, and sends it to the appropriate recipient.
如果从发送移动设备接收的即时消息中没有位置信息，用于接收即时消息的模块42触发位置模块45。位置模块45优选地发送位置请求到可能连接到地理信息系统的外部位置服务器本身。该位置请求包括意义明确地辨识发送移动设备的标识符。由于不是本发明的一部分，定位过程在此不作详细说明。The module 42 for receiving an instant message triggers the location module 45 if there is no location information in the received instant message from the sending mobile device. The location module 45 preferably sends location requests to an external location server itself, possibly connected to the geographic information system. The location request includes an identifier that unambiguously identifies the sending mobile device. Since it is not part of the present invention, the positioning process will not be described in detail here.
从位置服务器收到响应后，位置模块45在群控制模块43中存储接收的与发送移动设备的标识符相关的位置。群控制器检查该位置相对于已存储的位置是否改变，如果已改变则触发模块44传输即时消息到群控制器43中注册的以及属于发送移动设备的群的所有移动设备。然后模块44产生包括由发送移动设备提交的位置信息以及优选地包括存在信息的消息，并发送到恰当的接收方。Upon receipt of the response from the location server, the location module 45 stores in the group control module 43 the received location associated with the identifier of the sending mobile device. The group controller checks if the location has changed relative to the stored location and if so triggers the module 44 to transmit an instant message to all mobile devices registered in the group controller 43 and belonging to the sending mobile device's group. Module 44 then generates a message including the location information submitted by the sending mobile device, and preferably presence information, and sends it to the appropriate recipient.
